Brief summary
The present study explored the effects of the implementation of the Pythagorean Self Awareness Intervention (PSAI) on the dynamics of stress-related aging factors of immune cells in healthy volunteers and a cohort patients with type 2 diabetes mellitus . The primary aim was to evaluate the effectiveness of PSAI on two key biomarkers of biological age, telomere length and proteasome levels, indicative of the crosstalk between cellular oxidative status and replicative potential, with respect to metabolic, hormonal and mental status changes. Secondary aims of this study included reduction of depression, perceived stress, anxiety and the establishment of lifestyle changes to enhance the quality of everyday life, including better quality of sleep, eating behaviours and an overall healthier status.
Detailed description
Study design This non randomized non blinded parallel trial was conducted at the Laiko Hospital of Athens, Diabetes Centre, First Department of Propaedeutic Internal Medicine of Attica, Greece, from 4.10.2018 to 26.11.2019. The study protocol was approved by the Ethics Committee of the Laiko Hospital (protocol number 5134/5-4-19) and was in accordance with the declaration of Helsinki. All participants were enlisted in the study only after being fully informed by the researcher about the aims and procedures of the research and submitting written consent. Procedures Patients eligible for the above mentioned criteria were randomized in two groups: the group of healthy adult volunteers, and adults with type 2 diabetes who attended the outpatient diabetes clinic. This study was non-blinded, as patients and researchers were aware of the group assignment.
Interventions
BEHAVIORALPythagorean Self-Awareness Intervention(PSAI)
The PSAI is a mental, stress-management technique that promotes self-awareness, cognitive reconstruction and self-improvement based on the Golden Verses moral framework of the ancient Greek philosopher Pythagoras. The individual must practice the technique twice daily( at bed-time and in the morning, every day, at home) and through a 3-stage internal dialogue (recall of daily events, inspection of related thoughts and emotions and self-appraisal)is encouraged to detect wrong choices and unhealthy behaviours and initiate self-correction towards a healthier lifestyle.
